Abstract

The utility model relates to a maintenance-free iron case for coal blending experiments of a coke oven. The body of the iron case is a 500mm long cylinder with diameter of 380mm, two end heads of the cylinder are movable block boards made of steel plates, and holes with diameter of 10mm are uniformly distributed on the cylindrical surface and the block boards of the two end heads of the cylinder. Due to the cylindrical body, the iron case bears uniform and large pressure and is not easy to deform, in addition, the iron case has advantages of being simple in structure, running reliably, having good coal blending experiment effect and large economic benefits, and being maintenance-free for secondary use, and can be widely used for coal blending experiments of the coke oven.

Description

Non-maintaining coke oven coal blending experiment iron case

technical field:

The utility model relates to coke oven coal blending experiment iron case.

background technology:

400000 tons of tamping coke furnace coal blending experiments are the work that steelworks sticks at always, its effect is mainly rationally to utilize coal at a low price inferior to reduce mixed coal cost, high-quality coking coal, raising coke quality, guarantee coke pushing production direct motion that saving resource lacks, avoid accident to occur.The mode of the mixed coal coking tests doing at present can be divided into three kinds substantially: the one, and traditional pit kiln iron case experiment; The 2nd, the little Experiment Coke Oven coal blending experiment of 20kg, the 40kg researching and developing in recent years and 200kg; The 3rd, industrial coke oven actual production coal blending experiment.The relative merits of above-mentioned three kinds of coal blendings experiment are respectively: the first iron case experiment advantage is that iron case is placed directly in coke coking chamber, and it is identical that experiment condition and industrial coke oven are produced, and experimental data is accurate, making material less investment; Shortcoming is Yin Gaowen meeting gross distortion after iron case uses once, must after repairing, just can reuse, and has increased hand labor amount.The little Experiment Coke Oven advantage of the second is that experiment is flexible, and operation coal is quick; Shortcoming is that current consumption is large, procuring equipment investment is large, because coal capacity is few, coking chamber temperature is large from industrial coke oven difference, coking time is different, so experimental data and industrial coke oven difference are large, needs special messenger to operate.The third industrial coke oven coal blending production experiment advantage is that experimental data is real data, and can directly instruct production, shortcoming is that blending ratio can not significantly be adjusted, and experimental period is long; Extremely easily produce coke quality accident or difficult coke pushing and even take off burnt grade for industrial accident, reduction coke oven work-ing life.Solve above-mentioned these problems and become urgent need.

Utility model content:

in order to overcome the deficiencies in the prior art,the utility model provides a kind of simple in structure, reliable, secondary to use to be excused from a college course multiple new-type iron case.Non-maintaining coke oven coal blending experiment is the right cylinder of diameter 380mm, a long 500mm with iron box main body, and steel plate creative activity closure plate for two ends has the hole that equally distributed diameter is 10mm on cylindrical cylindrical surface and two ends closure plate.The utility model is because main body is right cylinder, and therefore pressure-bearing is stressed evenly, pressure-bearing is large and not yielding; Also have advantages of simultaneously simple in structure, reliable, coal blending experiment effect is good, economic benefit is huge, secondary use be excused from a college course multiple.

Brief description of the drawings:

Fig. 1 is the utility model front view;

Fig. 2 is the vertical view of Fig. 1.

Embodiment:

A most preferred embodiment of the present utility model, as figure, non-maintaining coke oven coal blending experiment is the right cylinder 1 of diameter 380mm, a long 500mm with iron box main body, steel plate creative activity closure plate 2 for two ends, on cylindrical cylindrical surface and two ends closure plate, having equally distributed diameter is the hole 3 of 10mm.

Claims

1. a non-maintaining coke oven coal blending experiment iron case, it is characterized in that: main body is the right cylinder of diameter 380mm, a long 500mm, steel plate creative activity closure plate for two ends has the hole that equally distributed diameter is 10mm on cylindrical cylindrical surface and two ends closure plate.
